To evaluate driving performances of aged drivers, driving experiments were executed for the elderly drivers with white matter lesions (WMLs) and without WMLs, respectively, in the same ages, and young drivers without WMLs. Before driving experiments, all of them undertook dynamic vigilance checker (DVC) test, a visual cognitive test. In the experiment, as an additional task, paced auditory serial addition test (PASAT), a calculation task given by voice, was imposed on drivers to examine the effect of the additional task on the driving performance. The driving skills were scored by an authorized police examiner, while driving parameters such as the steering angle, velocity of the car were measured by using a controller area network (CAN). The results showed that the drivers imposed with PASAT made more mistakes than when the drivers without PASAT, and scores of DVC test decreased with the growth of ages. Besides, the experiment indicated the possibility to estimate the driving skills by using CAN.
